I sometimes use posts from Facebook as inspiration to write various commentaries and critiques. While the harvest from Facebook is, on the whole, meager, recently Apprentice Gerald posted an interesting pic. Fortunately, the picture was not of a cute kitten nor a request to “Share if you like God”, but an easy to understand and through explanation of being an introvert.Being self aware, I've know for sometime that I'm an introvert, however this post explains to my satisfaction why I find people's mundane chatter so trying and tiring. I regret that I do not know Apprentice Gerald as well as I'd like to know him, but I do allow him to contribute to the website and that speaks volumes for those that understand.I've assumed the world is evenly divided between introverts and extroverts and there would be appropriately the same number of introverts to extroverts as there are men to woman. Future research will be needed to confirm this assumption and an enterprising researcher may find, on one hand, a correlation between introverts and the earth and water signs and, on the other hand, a correlation between extroverts and the fire and air signs.
